Extraterrestrial civilizations located within a radius of 100 light years from Earth are likely to know about the existence of humanity, but astronomers said that aliens may not be as friendly as humanity expects.
As astronomer Peter Ward said, aliens can be hostile to humans. He is sure that natural selection, if it took place on other planets, was carried out with all types of life. Only DNA equivalents could change, reports forbes.com.
If you compare with what is happening on Earth, you can see that each individual species cannot boast of altruism. It simply captures as many territories as possible and multiplies as actively as possible.
The same can happen if humanity collides with an intelligent extraterrestrial race – a war will begin for resources, territories, and so on.
Why do so many astrobiologists insist that high-functioning intelligence is going to lead to peace, love and understanding? That’s certainly not the case here on Earth. We don’t even respect our own species.
Here, all species we know of reproduce until they starve or otherwise become limited by space, says Ward. There is no altruism, every species on Earth would do what our species has done and take over as much of the resources as possible, he says.
However, regardless of the potential intentions of the aliens, the meeting with them, if it happens at all, must be carefully prepared.
